Delila is correct as she multiplying three negative numbers and determines that the solution will be negative.

As given in the question,

Let the three negative numbers be -x , -y , and -z.

Delia is multiplying three negative numbers

Multiply First two numbers

(-x) (-y) = + x y  as (-)(-) = +

Multiply by third numbers

(+x y) (-z) = -x y z   as ( +)(-) = -

Help with number 5 thx
Temka [501]

First, we find the area of the circle.

A = pi * r^2

A = pi * (1 cm)^2

A = pi cm^2

The area of the circle is pi cm^2.

The area of the triangle is also pi cm^2.

Now we use the area of a triangle.

A = (1/2)bh

(1/2)bh = A

(1/2)(3 cm)h = pi cm^2

(3 cm)h = 2pi cm^2

h = (2/3)pi cm

The exact height is \dfrac{2\pi}{3} ~cm

If you want an approximate height, then it is 2.09 cm.
